Abstract
A droplet jetting apparatus includes an actuator becoming deformed by a voltage application; an elastic body adhered to the actuator and becoming deformed in response to a deformation of the actuator; an ink chamber filled with ink, jetting a droplet of the ink in response to a deformation of the elastic body; a voltage information acquirer acquiring a voltage information of the actuator; and a sense/decider sensing at least any of an abnormality in the ink chamber, a failure of the actuator, and a defective adhesion between the actuator and the elastic body based on the voltage information, and deciding whether or not the ink is being jetted normally.
